Miikka Silfverberg Yes, but the first impression seems ironic or counter-intuitive unless one knows about chemistry. I'm a retired engineer whose last project was to re-design a specialized electroplating instrument that was being destroyed by a wide variety of very harsh chemistry used for electroplating several metals, including platinum, gold, iridium, nickel, zinc, titanium & others. The project was challenging because nearly all the working parts, including high & low voltage electronics, structures, containers, valves, pressure/vacuum controls, which had to be replaced with mostly teflon-coated components, platinum or 316 stainless. Then, there were gobs of tubing & fittings to replace (all FEP, PEEK or teflon). Chemistry run through it included concentrated acids & bases at both ends of the PH scale, bleach, hydrogen peroxide and piranha. Lots of pricey, specialized labware were required. Although I had worked with many chemists for decades, that final project really got me thinking about & researching inert materials. Chemistry was never my strong suit, so it was an education for me. Generally, I've got to say that automating chemistry processes was very interesting work, and direly needed to keep PhD lab-rats from becoming disenchanted with the tedium in their lab work. I'd recommend to engineering students that they get a good dose of chemistry & really learn it well because the demand for engineers will focus in that professional arena and other scientific endeavors involving chemistry as part of a process. Increasingly, engineering is becoming mostly scientific.

***** Thank you! :) I found this very interesting! Cool that changing one atom can have such an effect! Nevertheless, this was not an easy read with my chemistry background... So what I'm going to say may be total garbage :D As far as I could understand, they present several reasons why fluorination could be useful in increasing bio-availability. Stability is one of them. In Section 2, they seem to explain how increased stability of the fluorinated compounds increases bio-availability: it makes them more resistant to metabolic enzymes and thus more likely to reach the site where they can be medically active. However, as far as I understood, they also say fluorination can modify the basicity or acidity of parts of the compound, increase binding affinity to proteins and change the form of the compound (or rather the preference between different isomers of the molecule). A lot of factors besides stability are at play apparently! Both properties of fluorine itself and properties of the target protein factor in. The combination of biology and chemistry is really interesting! Though it also seems quite tricky :)

Food containing many small saccharids is an ideal medium for those, accelerating the process. Besides strengthening the teeth by reacting with apatite, toothpaste also helps generating a high pH, prohibiting the growth of microorganisms.

The general consensus is that it improved the quality of our teeth. An over-exposition is possible (dental fluorosis) but not achieved by normal means. However many countries stopped the fluoride addition because there are many other sources, mostly table salt containing fluoride. It is sometimes considered forced medication and there is still an ongoing debate whether it's necessary or even harmful.

F2 is Fluorine, NaF is Sodium Fluoride, NaCl is sodium chloride, MgBr2 is magnesium bromide, ect.

Do these fluoride compounds enter the blood supply when ingested (like tin fluoride or whichever type of fluoride is added to some water supplies). If so, is it possible that ingesting fluoride compounds could become dangerous when these compounds come into contact with reactive intermediates especially during the normal metabolic process? Such as reactive oxygen species or other radical species? I used fluvoxamine, a fluorine containing anti depressant for a little while so i know fluorine is a great enzyme de- activator.

It may be as dangerous as the radioactive materials.. at least you can shield yourself to a degree. Nothing worse than standing near plumbing carrying uranium product, and the fluorine eats through a pipe.

Good point but not quite. When the tin fluoride dissociates it splits into tin ions and fluoride ions. The fluoride ions are the non-reactive state of fluorine since they have already accepted electrons from the tin. Fluorine is dangerous because it has not accepted electrons from anything yet and will take them from just about anything. On a molecular level the fluoride is made of individual fluorine atoms with a negative charge and fluoride is made of a pair of fluorine atoms with no charge.

1:11 Because of the statement "Fluorine reacts with the whole periodic system, except for Helium and Neon": Are there really compounds of Argon and Fluorine known, now?

When the jet of F2 burns directly through the iron, I wonder what happens to the unreacted gas that now finds itself in the atmosphere? My guess is that it immediately finds some humidity, releasing HF and O2. That can't be very nice to breathe in.

It might also react with the nitrogen in the air and produce NF3, because although nitrogen is very inert, fluorine is extremely reactive and can pull some molecules apart(which makes those N atoms very reactive too) and react with it, and nitrogen makes up about 80% of the air.

I like the reaction with Iodine. Looks like Apophysis!

@vtblowschunks would basically do the same as a flame thrower? set stuff on fire its probably to expensive to make and other stuff works better for cheaper

so fluorine is about as energetic per unit when it combines as propane when it combusts, except you dont need a spark or ignition source. Easy lighter?

What would happen if you put that liquid flourine Into a 6 inch thick solid glass Container and Sealed it, melting it on the outside so that it’s one solid piece with no air on the inside And allowed it to warm up to room temperature?

3:05 I believe iron fluoride is greenish stuff in the middle.
